Expand your creativity


"I recommend this course to everyone who loves this wonderful genre and wants to deepen their musical knowledge."
Helena Rüegg

During the last few years, we have been teaching online Tango Arranging to musicians who requested our writing services before. Now they can write their own arrangements in a professional level. Due to the success of this lessons, we decided to offer the same course to everyone who wants to write original arrangements.

Tangoideas wants to provide you with tools to develop your creativity through the writing of arrangements. That is why this course is thought and designed step by step with the aim of delving into each of the musical aspects in the art of arranging, from solo instruments to large ensembles.

We know that every musician has different levels of knowledge, so we decided to offer this course in modules. Although we recommend taking the full course to have a better understanding, if you are only interested in a part, you can customize it by selecting the modules you want, at a different price.

Opinions from our students

"We started the TANGO IDEAS online course in tango arrangement in march 2021 and we still enjoy every minute of the course. Although we already had some experience with arranging, Matias and Gustavo really brought us to a much higher level. Every lesson has a subject to be learned like melody, harmonization, phrasing, marcato etc. The lessons are two hours each and are full of music examples of the different orchestras and musicians. Every lesson is in very good balance and we always have a lot of fun. It’s really two hours of music talk and laughter. And after every lesson we get the material and our homework assignments. We can truly say that we listen to tango in a totally different way. We hear things we never heard before and we use them in our arrangements and playing. We highly recommend this course to everyone who wants to learn to arrange Argentinian tango. It’s simply the best course in the word, given by two very experienced arrangers, musicians and good teachers."

"30 years ago I discovered the bandoneon in Buenos Aires, which has changed my entire life. Since then I have dedicated myself to the studies of the bandoneon and the Tango genre. I have studied a lot in Argentina with the great masters, at the Avellaneda School of Popular Music and in the tango department of the Rotterdam Codarts Conservatory. I have learned a lot with all these teachers. But since we started our arrangement classes with Gustavo and Matías at the beginning of March 2021, all the parts of my knowledge are being completed and forming a whole image. The method that Matias and Gustavo have developed is very clear and very detailed. It feels like they've put a lot of thought into it to condense all the information into simple words and steps that can be easily understood as a great meal recipe. I finally dare to start making my own arrangements, a task that until this course seemed impossible to me. In addition to the information that they transmit to us, Matias and Gustavo are doing it with such joy and passion for Tango and all the great composers and arrangers who have developed this genre that it is a pleasure to listen to them. And at the end of each class I'm glad to meet them again for a next lesson hoping that this musical path shared by our same passion never ends to learn more and more. I recommend this course to everyone who loves this wonderful genre and wants to deepen their musical knowledge."
